COMPANY, OF JACKSON, MICHIGAN, A CORPORATION OF DELAWARE.

SPRING STRUCTURE.

Application filed February 25, 1921.

To all whom it may concern:

Be it known that I, Drsmn H. VAN Hove, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented new and useful Improvements in Spring Structures, of which the following is a specification.

This invention relates to spring structures.

One object of the invention is to provide a spring structure for automobile or other seats, embodying among other characteristics, upper and lower frames connected together by relatively stitt' border springs within which is disposed a group of springs of shorter length surrounded by an intermediate frame, constituting a deck of auxiliary springs within the border springs and upon which deck may be loosely mounted a cushion which may fit within the confines of the upper portions of the border springs and which may consist of pocketed springs.

Another object of the invention resides in the provision of a spring structure including a base frame, relatively stiff border springs connected to the base frame, a deck of'relatively short springs on the base frame within the border springs, and arranged to provide arecess in the top of the structure for the reception of a cushion adapted to be mounted directly upon said deck of springs, the cushion being composed preferably of cylindrically shaped springs of very light gage wire with each spring arranged within a pocket of fabric or separated by a fabric or other suitable material to prevent the springs from rubbing against one another and causing a noise.

A still further object is to provide a spring structure having a. comparatively stiff edge and an exceedingly soft and pliable center to provide for the ease and comfort of the rider.

With these and other objects in view the invention consists in the novel construction, combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended, itbeing understood that various changes in the form, proportion, and minor details of construction, with- .in the scope 'of the clams, may be resorted to without departing from the spirit or sacrificlng any of the advantages of the invention:

Specification of Letters Patent;

Patented Aug. 16, 1921.

Serial No. 447,754.

supporting members 8 and being clipped at their upper ends as at 9 to the upper frame.

A group of relatively short springs 10 are mounted upon said, supporting members 8 and may be of double cone or other type and are of a height substantially one-half the height of the border springs 7. A frame 11 may be connected to the upper convolutions of the springs 10 forming a border for the upper ends of the said springs. This frame may be connected by links 12 to the border springs so as to prevent the lateral shifting of the border frame 11 and the group of springs 10. If desired, a wire cloth or other netting 13 may be connected to the border frame 11 across the other ends of the group of springs 10. This group of springs 10 with their frame 11, with or without the netting 13, form what constitutes a deck within the structure and within the confines of the upper portions of the border springs.

A cushion is adapted to be supported within the structure upon said grou or deck of springs 10. This cushion preferably consists of pocketed springs. In any event the cushion is composed preferably of relatively light gage wire springs confined within an enveloping member such as fabric. In one embodiment of the invention, the cushion is composed of rows of very light cylindrical shaped springs 1i, arranged-close together, with parallel strips of cotton, canvas or an" other suitable fabric 15 arranged between ad jacent rows of springs to prevent direct contact of the oonvolutions of one row of'springs with the convolutions of the row of adjacent springs .and thereby preventing noise. A marginal strip of cotton canvas or other fabric material 15' incloses the outer springs 14.

The upper and lower edges of the mar 'nal strip 15' and the upper and lower en 5 of the vertical strips of fabric 15 are connected to upper: and lower sheets of burlap or other suitable material 16 and 17, respectively.

When the cushion is thus formed it is let down into the spring structure and rests directly upon the group or deck of springs 10, overhanging the border frame 11 with the edges of the cushion lying close to the border springs. This cushion may be connected to the border springs or other upper frame or in any other manner fastened.

against accidental removal from off the deck of springs 10 as for instance, if the structure should be turned upside down or set on one edge. In actual use of the structure, there is no necessity of fastenin the same to the spring'structure because in the customary methods of upholstering, the upholstering cover, together with the upholstering mattirial, would maintain the cushion in proper ace. F From the foregoing. it will be seen that there. is provided an exceedingly resilient and soft spring cushion for automobiles or other purposes. The border wires are relatively did and the center of the structure isexccedingly soft and pliable, particularly in view of the relatively light gage wire of which the cushion springs are composed. The

structure may be said to consist of a spring structure embodying a frame, border springs, a lower deck of springs, and an upper deck of springs, the upper deck being readil lower dec of springs, and the upper deck being composed of springs of considerably lighter gage wire than the springs of the lower deck, thereby providing for softness, pliability and providing for ease and comfort for the rider.

\Vhat is claimed is: 1. In a spring structure, an upper frame, a lower frame, borderspringsarrangedwithin the upper and lower frames, a group of lower springs arranged between the frames and within said border s rings, a group of up per-springs arrange within the frame and within the bidder springs and mounted upon ,said lower group of springs, the upper springs of said group being of lighter gage wire than the springs of the lower group, and strips of fabric arranged between the springs of said upper group-2f springs to prevent noise.

2. Ina spri structure, immpperframe, lower framef iorder springs arranged between the frames, 5. grou of lower springs arranged within the bar or 5 rings, and a fabric covered set of relative yhght gage wire springs arranged close-together and supported upon said lower group of springs. 3. In a. spring structure, an upper frame,

detachable with relation to the a lower frame, border springs arranged between the frames, groups of upper and lower\ springs arranged between the frames and within the border springs, the springsv and mounted upon-said group of springs and composed ofsprings of relatively light wire, all of the springs of said cushion being pocketed in fabric.

5. In a spring structure, a base frame, border springs connected to the base frame, a group of springs of less height than the border springs forming a deck within the border springs, and a cushion composed of 5 rings and fabric adapted to rest on said eck and within the border springs.

6. In a spring structure, a frame, border springs, mounted upon the frame, a group of lower springs arranged on the frames and within the border springs, and-a fabric covered set of relatively light gage wire springs arranged close together and-supported upon said lower group of springs.

7. In a spring structure, a frame, border springs arranged on the frame, a group of lower springs arranged on the frame and within said border springs, a group of upper springs arranged between the frame and within the border springs and supported on said lower group of springs, the upper group of said springs being of lightergage wire than the springs of the lower group and meansbetween said upper and lower groups of springs to prevent noise.-

8, In a spring structure,.a frame, border springs supported on the frame, a group of springs of less height than the border springs arranged within the-border springs and orming a deck, a frame for said group of springs, connected at the upper endsof the latter, and an inclosed group of springs amn (1 within the border s rm and supports upon the deck formed yt e aforesaid group'of springs. 1 I 9.
